| Abstract [eng] |
This work presents the overview of the requirements for the compaction and deformation module while installing roads, paths, ground landings and substrates of the ground, filling the trench, water-permeable. The methods for determination of compaction ratio, dynamic deformation modulus and static deformation modulus used for landings and foundations are being analyzed. Since the compaction ratio and the deformation modulus can be determined by various methods, different test methods for determining these parameters were implemented in test road stretches on different road pavements. The evaluation of interdependency of these indicators, theoretical and practical, was made. According the received results, the most accurate method for determining the compaction ratio is the density determination using ring. In order to determine the deformation most likely to be performed is the test for determining the dynamic deformation module. It has been stated that the static and dynamic deformation modulus changes accordingly. While evaluating the compaction indirectly, it was found that the correlation between the deformation modulus ratio and the compaction ratio is weak. |
